A total recovery of more than97% of the gold and silver is made by flotation, while the combined flotation-cyanidation process gives an overall extraction of 95%. The installation is much more compact and its capital cost far less than one embodying fine grinding and cyaniding of the whole tonnage, and it can be run with lower operating, maintenance, and depreciation costs.

In the case of this study, it is assumed that a separate lead-copper circuit is not warranted. The flotation section consists oftwo 10-cell “Sub-A” FlotationMachines, one for the lead-copper and the other for the zinc. The launder arrangement and pulp flow is the same for both machines and provides double cleaning of the rougher concentrates.
Water is added for 15 min. to separate the gangue in the cells from the high-grade concentrate, after which a product consisting of sulphides and coarse gold is removed through a 4-in. plug valve equipped with a locking device. Each day approximately 400 lb. of material worth $2000 to $3000is recovered.

Oxidic ore can be concentrated using flotation or, if it has a low acid demand, it may be economic to acid heap leach the stockpile. The recovery of these copper minerals by flotation or hydrometallurgy from ores, typically containing0.5%TCu (open pit mines) and 1-2%TCu (underground mines)...
The frothflotationtechnique was originally developed in about 1910 to raise thecopperconcentrations of the strip-mined ores of Bingham Canyon, near Salt Lake City [9], and was further perfected for the differentialseparationof lead, zinc, and iron sulfides at Trail, B.C., at about the same time [10].Flotationtechnologies are now widely ...

Manycopper–goldconcentrators have a combination of flashflotationand gravityseparationin the milling circuit to enhance overall freegoldrecovery. The reason for the inclusion of gravityseparationat these concentrators is that the coarse freegoldis not recovered effectively in the flashflotation cell.
The most commonly used collectors forthe flotation of native gold, othergoldminerals and auriferous sulphides are the xanthates, exemplified by sodium ethyl xanthate (NaC2H5OCSS) (5, 35 ...
